Cadillac Escalade ESV wet floorboards possibly due to clogged AC on Cadillac Escalade ESV

Problem overview

Some Cadillac Escalade ESV owners report experiencing wet floorboards, particularly on the passenger side, without any coolant smell or stain. This issue may stem from a clogged AC condensate drain line, which can lead to water accumulation on the floorboard. Additionally, problems with sunroof drains could contribute to this wetness, as well as non-draining A/C boxes and wiring pass-throughs that may cause leaks, potentially damaging the A/C control module and carpeting. To effectively address this problem, it is crucial for owners to identify the specific cause of the water leakage and consult a professional mechanic to inspect and clear any clogged AC drains, thereby preventing further water damage to the vehicle.
